Pinecil V2 interface library

Overview

Pinecil is a lightweight Python library designed to inetrafce with Pinecil V2 soldering iron.

Requirements

• Python 3.9 or higher
• bluez

Installation

pip install pinecil

Usage Example

A complete from-scratch example:

from pinecil import find_pinecils # if running in a cloned repo, use `from src.pinecil`
import asyncio

async def main():
    devices = await find_pinecils()
    iron = devices[0]
    await iron.connect()
    settings = await iron.get_all_settings()
    await iron.set_one_setting('SetTemperature', 250)
    await iron.save_to_flash() # this is required to preserve settings after powering off
    info = await iron.get_info()
    live = await iron.get_live_data()
    print(settings)
    print('----------')
    print(info)
    print('----------')
    print(live)

if __name__ == '__main__':
    asyncio.run(main())

If you already know the address of your pinecil, you can use it directly:

from pinecil import BLE, Pinecil
import asyncio

if __name__ == '__main__':
    p = Pinecil(BLE('<your-address>'))
    asyncio.run(p.get_all_settings())

To find addresses of all pinecils nearby:

from pinecil import find_device_addresses
import asyncio

if __name__ == '__main__':
    asyncio.run(find_device_addresses('pinecil'))

Testing

poetry shell
pytest -v
# for development convenience:
ptw --runner 'pytest -v'

Publish to test.pypi

You will need a PyPi token first: https://test.pypi.org/manage/account/token/

poetry config repositories.test-pypi https://test.pypi.org/legacy/
poetry config pypi-token.test-pypi pypi-XXXXXXXX
poetry build
poetry publish -r test-pypi

Exceptions

• ValueOutOfRangeException: Attempting to set a settings value that is out of range.
• InvalidSettingException: Setting does not exist.
• DeviceNotFoundException: Indicates the device was not found.
• DeviceDisconnectedException: Indicates the device was disconnected.

Classes and Functions

Class: Pinecil

• Constructor: __init__(self, ble: BLE): Initializes Pinecil with BLE instance.
• Properties:
  • is_connected -> bool: True if Pinecil is connected.
• Methods:
  • connect(self): Connects to Pinecil.
  • get_all_settings(self) -> Dict[str, int]: Retrieves all settings.
  • set_one_setting(self, setting: str, value: int): Sets a single setting - does not save to flash.
  • save_to_flash(self): Saves all settings to flash.
  • get_info(self) -> Dict[str, str]: Retrieves basic Pinecil info.
  • get_live_data(self) -> Dict[str, int]: Retrieves live data.

Class: BLE

• Constructor: __init__(self, address: str): Initializes BLE device wrapper.
• Properties:
  • is_connected -> bool: True if connected to the device.
• Methods:
  • ensure_connected(self): Connects to the device if not connected (does nothing if connected)
  • get_services(self) -> List[str]: Gets list of services.
  • get_characteristics(self, service_uuid: str) -> List[BleakGATTCharacteristic]: Gets characteristics of a service.
  • read_characteristic(self, handle: BleakGATTCharacteristic) -> bytes: Reads value of a characteristic
  • write_characteristic(self, handle: BleakGATTCharacteristic, value: bytes): Writes value to a characteristic.

Function: find_device_addresses

• Description: Finds devices matching a given name and returns their UUIDs
• Returns: List[str]: List of device addresses.

Function: find_pinecils

• Description: Finds nearby pinecils and returns their list.
• Returns: List[Pinecil]: List of found device instances.
